A recent report found 46% of parents agreed that their child knew more about the Internet than they did. And now new research shows parents are turning to their children for lessons in technology.

The new study of around 1,000 parents showed that 67% of parents have asked their teenager children for technology-related advice. 44% have asked their teenager for help using the Internet, and 41% have received teen advice about how to use the TV or home entertainment system.

Ahad Surooprajally, a father of five children, says his children help him with technology in the home. “They’ve grown up surrounded by technology,” he explains. “We have four computers and four iPads in our house. If I want to know something technical they're the ones I go to.”

He says his nine-year-old son Habeeb is the only person in the house who really understands the TV. So he tells Habeeb which film he wants to watch and Habeeb connects his mobile phone to the TV. “You teach your kids everyday life lessons, but the tables are turned when it comes to technology,” says Ahad.

As well as learning how to use technology properly, there is another advantage of parents asking their children to help them understand the digital world. They may be able to get a better understanding of what their kids are doing online.

Will Gardner of the charity Childnet International says, “We have to continuously encourage parents to find out more about what their children are doing online. If the kids are using a social networking site, get them to show you around it if you are not using it already.”

A. Few parents trust their children to give them advice.

B. About half of the parents have no idea how to use a computer.

C. Most teenagers know more about the Internet than their parents.

D. Over two-thirds of parents turned to their teenagers on tech matters.

2.What does the underlined part “the tables are turned” probably mean?

3.Which of the following can be the best title for the text?

A. Internet: Open to our kids too early

Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time, according to the findings of research carried out at Aston University's School of Life and Health Sciences. The findings suggest there may be some scientific basis to the '5 second rule' --- the belief about it being fine to eat food that has only had contact with the floor for five seconds or less. Although people have long followed the 5 second rule, until now it was unclear whether it actually helped.

The study, undertaken by final year Biology students and led by Anthony Hilton, Professor of Microbiology at Aston University, monitored the transfer of the common bacteria from a variety of indoor floor types such as carpet, cement floor to toast, pasta, biscuit and a sticky sweet when contact was made from 3 to 30 seconds. The results showed that: Time is a significant factor in the transfer of bacteria from a floor surface to a piece of food; and the type of flooring the food has been dropped on has an effect, with bacteria least likely to transfer from carpeted surfaces and most likely to transfer from cement flooring surfaces to moist foods making contact for more than 5 seconds. Professor Hilton said: "Consuming food dropped on the floor still carries an infection risk as it very much depends on which bacteria are present on the floor at the time.”

The Aston team also carried out a survey of the number of people who employ the five-second rule. The survey showed that: 87% of people surveyed said they would eat food dropped on the floor, or already have done so. 55% of those that would, or have, eaten food dropped in the floor are women. 81% of the women who would eat food from the floor would follow the 5 second rule. Professor Hilton added: "Our study showed surprisingly that a large majority of people are happy to consume dropped food, with women the most likely to do so. But they are also more likely to follow the 5 second rule, which our research has shown to be much more than an old wives tail."

1. Eating food dropped on the floor still carries an infection risk because it relies on________ at that time.

A. the type of bacteria B. the carpet

C. the cement floor D. the surface of table

2.The passage is developed probably by __________.

A. time B. space C. contrast D. example

3.How did Professor Hilton feel after analyzing how many people chose to eat dropped food?

A. Satisfied B. Astonished

C. Puzzled D. Upset

4.What is the main idea of this passage?

A. The food which is dropped on the floor can be eaten safely.

B. The bacteria have no negative effect on the safety of food.

C. A research on the safety of food dropped on the floor is undertaken.

D. People surveyed in the research are willing to accept the idea.
